Just to know what your Sony Bravia 60LX903 supports, you can use Intel Tool:- Install Intel UPnP tools- run Device Spy- It should list all your UPnP device and among them your device (eg TV, console, etc)- Expand the device's tree and find service: urn:upnp-org:serviceId:ConnectionManager:1- Expand that and double click on GetProtocolInfo(...). - Click on Invoke and the result is in field Sink.- Post it
